Two parts of computer simulation depicting a dynamic orbital skyhook, a cable in a sub synchronous orbit that rotates to touch the planet surface. The first part shows a touch down and take off of an end of the cable at a hypothetical space port in Africa. The second segment shows an animated diagram of the cable skyhook as it rotates and orbits to "walk" the planet surface. Shot directly off a video monitor - low image quality. Digitized in 2006.
